Earthworms influence a wide range of soil properties. They are affected by practices that perturb the soil or change organic inputs. This study compared populations in UK organic and conventional rotations differing in ...

The compensatory responses of juvenile gibel carp and Chinese longsnout catfish to four cycles of 1 week of feed deprivation and 2 weeks of satiation feeding were quantified as part of a study designed to determine feeding ...

Compensatory growth (CG) is a phase of accelerated growth when favourable conditions are restored after a period of growth depression. CG reduces variance in size by causing growth trajectories to converge and is important ...

To investigate the compensatory growth responses of the carnivorous Chinese longsnout catfish a 7-week study was performed at 28 °C. Juvenile longsnout catfish weighing a mean of 13.14 g were starved for 0 (control), 1 ...

Compensatory growth responses are made by individual fish to restore their original growth trajectory following a period of growth depression. Little is known about whether diseases impact a fish's capacity for growth ...

Different protocols of food deprivation were used to bring two groups of juvenile three-spined sticklebacks Gasterosteus aculeatus to the same reduced body mass in comparison with a control group fed daily ad libitum. One ...

Complex combinations of historical and local-regional processes determine the assembly of ecological communities. We investigated such processes in the Hawaiian introduced avifauna, comprising 140 years of historical records ...

The purpose of this chapter is to examine the factors most likely to influence the dynamic grass-legume relationships in established pastures. Attention has necessarily been focused on the economically important ryegrass ...

Grain legumes, such as peas (Pisum sativum L.), are known to be weak competitors against weeds when grown as the sole crop. In this study, the weed-suppression effect of pea–barley (Hordeum vulgare L.) intercropping compared ...

There is currently much debate about the relative importance of two contrasting mechanisms thought to be involved in regulating plant communities. One of these mechanisms is thought to result from species which possess ...

The genus Sorangium synthesizes approximately half of the secondary metabolites isolated from myxobacteria, including the anti-cancer metabolite epothilone. We report the complete genome sequence of the model Sorangium ...

The complete mitochondrial genome of Flustrellidra hispida (Bryozoa, Ctenostomata, Flustrellidridae) was sequenced using a transposon-mediated approach. All but one of the 36 genes were identified (trnS2). The genome is ...

We appraise the present geographical extent and inherent knowledge limits, following two decades of research on elevated CO2 responses in plant communities, and ask whether such research has answered the key question in ...

This paper briefly discusses polyploidy in plants as a consequence of the combined effects of interspecific hybridization and allopolyploidy, and describes outcomes in some species when divergent genomes are brought together ...

A combination of genetics and archaeology is revealing the complexity of the relationships between crop plants and their wild ancestors. Archaeobotanical studies are showing that acquisition of the full set of traits ...

Subsets of proteins involved in distinct functional processes are subject to different selective pressures. We investigated whether there is an amino acid composition bias (AACB) inherent in discrete subsets of proteins, ...
